anonymous · Answer

start by finding the radius of the cylinder. 

then volume of a cylinder is 

V=π×r2×h


r = radius and h = height

substitute and find the volume of gold in the cylinder. 

the last part is the number of cylinders. 

it will be 

volume of the block divided by volume of a cylinder. 

hope this helps
